- Background: Educational environments are considered important in strengthening students’ health status and knowledge, which are associated with good educational outcomes. It has been suggested to establish healthy universities based on a salutogenic approach – namely, health promotion. The aim of this study was to describe health-promoting resources and factors among first-semester students in higher education in healthcare and social work.Methods: This cross-sectional study is based on a survey distributed among all students in seven healthcare and social work programmes at six universities in southern Sweden. The survey was carried out in 2018 using a self-reported, web-based questionnaire focussing on general health and well-being, lifestyle factors together with three validated instruments measuring health-promoting factors and processes: the Sense of Coherence (SOC) scale, Salutogenic Health Indicator Scale (SHIS) and Occupational Balance Questionnaire (OBQ).Results: Of 2283 students, 851 (37.3%) completed the survey, of whom 742 (87.1%) were women; 722 (84.8%) were enrolled on healthcare programmes, and 129 (15.2%) were enrolled on social work programmes. Most reported good general health and well-being (88.1% and 83.7%, respectively). The total mean scores for the SOC scale, SHIS and OBQ were, respectively, 59.09 (SD = 11.78), 44.04 (SD = 9.38) and 26.40 (SD = 7.07). Well-being and several healthy lifestyles were related to better general health and higher SOC, SHIS and OBQ scores. Multiple linear and logistic regressions showed that perceived well-being and no sleeping problems significantly predicted higher general health and higher SOC, SHIS and OBQ scores. Being less sedentary and non-smoking habits were significant predictors of higher SOC.Conclusions: Swedish students in higher education within the healthcare and social work sector report good general health and well-being in the first semester, as well as health-promoting resources (i.e. SOC, SHIS and OBQ), and in some aspects, a healthy lifestyle. High-intensity exercise, no sleeping problems and non-smoking seem to be of importance to both general health and health-promotive resources. This study contributes to knowledge about the health promotive characteristics of students in the healthcare and social work fields, which is of importance for planning universities with a salutogenic approach.

- The aim of this paper was to evaluate whether primary health care staff's referral of patients to perform an electronic screening and brief intervention (e-SBI) for alcohol use had a greater impact on change in alcohol consumption after 3 month, compared to patients who performed the test on their own initiative. Staff-referred responders reported reduced weekly alcohol consumption with an average decrease of 8.4 grams. In contrast, self-referred responders reported an average increase in weekly alcohol consumption of 2.4 grams. Staff-referred responders reported a 49 reduction of average number of heavy episodic drinking (HED) occasions per month. The corresponding reduction for self-referred responders was 62. The differences between staff- and self-referred patient groups in the number who moved from risky drinking to nonrisky drinking at the followup were not statistically significant. Our results indicate that standalone computers with touchscreens that provide e-SBIs for risky drinking have the same effect on drinking behaviour in both staff-referred patients and self-referred patients.

- Dry vaccine formulations for sublingual administration would provide great advantages for public health use, especially in developing countries, since they are easy to administer and might also have improved stability properties. This study investigates the influence of protein release rate from mucoadhesive twolayer tablets on the elicited antibody responses after sublingual immunization. Two fast release tablets, one based on a mixture of lactose and microcrystalline cellulose (MCC) and one protein coated ethylcellulose (EC) tablet, and three hydrophilic matrix tablets with extended release (ER) properties based on HPMC 90 SH 100000 or Carbopol® 974-P NF were tested. The in vitro release profiles of the model protein ovalbumin (OVA) from these tablets were characterized and correlated to the in vivo potential of the tablets to induce an immune response after sublingual immunization in BALB/c mice. It could be concluded that a tablet with fast protein release elicits antibody titres not significantly different from titres obtained with OVA in solution, whereas low immune responses were observed with a slow release of OVA from the ER formulations. Thus, an ER tablet seems not favorable for vaccine delivery to the sublingual mucosa. Thus, we can present a fast releasing tablet formulation with attractive features for sublingual immunization, whereas the use of ER formulations for sublingual vaccination has to be investigated more in detail.

- A promising liquid killed multivalent whole-cell plus enterotoxin B-subunit oral vaccine against enterotoxigenic Escherichia coli (ETEC), the primary cause of diarrhea among children in low-income countries and travelers to these areas, has recently been developed and tested in preclinical and phase-I and phase-II clinical studies. The vaccine contains killed E. coli bacteria over-expressing the main ETEC colonization factors (CFs) CFA/I, CS3, C5 and C6, and a recombinant enterotoxin B subunit protein (LCTBA) given together with a recently developed enterotoxin-derived adjuvant, dmLT. A dry-powder vaccine formulation should be advantageous especially for use in low-income countries. Here we describe a method to produce a dry-powder formulation by freeze-drying of the vaccine using inulin as stabilizer. Although not completely preventing aggregation of bacteria during freeze-drying, the stabilizer provided both improved overall bacterial morphology and almost complete recovery of the CF and B subunit antigens. Most importantly, oral-intragastric immunization of mice with the freeze-dried vaccine together with dmLT adjuvant elicited strong intestinal mucosal and serum antibody responses against all vaccine antigens, which were comparable to those achieved with the liquid vaccine. Our results indicate the feasibility to use freeze-drying with inulin as stabilizer for preparing a dry-powder formulation of the novel ETEC vaccine with retained oral-mucosal immunogenicity compared to the liquid formulation. © 2016 Elsevier B.V.

- HpaA is a Helicobacter pylori-specific lipoprotein that has been shown to be an effective protective antigen for mucosal vaccination against H. pylori infection in mice. However, detergents are needed for the purification of full-length HpaA (HpaA(full)), which might confer toxicity, thus making HpaA(full) unsuitable for use in a human vaccine. We here describe a recombinantly produced truncated version of HpaA (HpaA(trunc)), which is easily purified without the use of detergents. Evaluation in the murine H. pylori infection model showed that sublingual immunization with HpaA(trunc) was equally immunogenic and protective as immunization with HpaA(full). Immunization with a combination of HpaA(trunc) and recombinant UreB protein induced strong immune responses to both antigens and importantly had a strong synergistic effect on protection, associated with synergistically increased expression of IL-17 in the stomach. Notably, sublingual immunization with HpaA(trunc) and UreB was superior to corresponding intragastric immunization with regard to the level of protection induced. In conclusion, HpaA(trunc) is a promising, readily produced, non-toxic recombinant antigen for inclusion in a mucosal vaccine against H. pylori infection, which may preferably be given sublingually together with UreB.

- We describe here the development of stable classical and El Tor V. cholerae O1 strains of the Hikojima serotype that co-express the Inaba and Ogawa antigens of O1 lipopolysaccharide (LPS). Mutation of the wbeTgene reduced LPS perosamine methylation and thereby gave only partial transformation into Ogawa LPS on the cell surface. The strains express approximately equal amounts of Inaba-and Ogawa-LPS antigens which are preserved after formalin-inactivation of the bacteria. Oral immunizations of both inbred and outbred mice with formalin-inactivated whole-cell vaccine preparations of these strains elicited strong intestinal IgA anti-LPS as well as serum vibriocidal antibody responses against both Inaba and Ogawa that were fully comparable to the responses induced by the licensed Dukoral vaccine. Passive protection studies in infant mice showed that immune sera raised against either of the novel Hikojima vaccine strains protected baby mice against infection with virulent strains of both serotypes. This study illustrates the power of using genetic manipulation to improve the properties of bacteria strains for use in killed whole-cell vaccines.

- ObjectiveThe aim was to explore whether occupational balance is associated with health, health-promoting resources, healthy lifestyle and social study factors among students during higher education within healthcare and social work.DesignThe study has a multicentre repeated cross-sectional design. Data were collected via a self-reported, web-based questionnaire based on the validated instruments: the 11-item Occupational Balance Questionnaire (OBQ11), the Sense of Coherence (SOC) Scale, the Salutogenic Health Indicator Scale (SHIS) and five questions from the General Nordic Questionnaire (QPS Nordic) together with questions about general health and lifestyle factors.SettingStudents at six universities in western Sweden at one of the following healthcare or social work programmes: biomedical scientists, dental hygienists, nurses, occupational therapists, physiotherapists, radiology nurses and social workers. Participants Of 2283 students, 851 (37.3%) participated.ResultsThe students experienced that occupational balance increased during education. The total OBQ11 score was higher among students in semesters 4 and 6/7, compared with semester 1 students. Students with higher OBQ11 also reported higher SOC throughout their education, while health seemed to decrease. Students who reported higher levels of OBQ11 reported lower levels of health and well-being in semesters 4 and 6/7, compared with semester 1. There was an opposite pattern for students reporting lower levels of OBQ11.ConclusionsThe association between higher levels of OBQ11 and lower levels of health and well-being is remarkable. There is a need for more research on this contradiction and what it means for students’ health and well-being in the long run.

- The approach of inducing protective immunity against cholera by oral vaccination with killed whole Vibrio cholerae cells is effective, but the complexity of current cholera vaccines makes them difficult and relatively expensive to manufacture, especially if recombinant cholera toxin B subunit is included in the formulation. In an effort to simplify the composition of a new generation of oral cholera vaccines we have generated a novel non-toxigenic candidate vaccine strain of V. cholerae O1 that stably expresses both the Ogawa and Inaba serotype antigens on its surface. This was done by introducing a functional wbeT gene without a functional promoter into the chromosome of an O1 Inaba strain. The resulting low levels of expression of the wbeT gene product allowed for the desired partial serotype switching. This strain (MS1342) can potentially replace the three virulent strains used in currently manufactured cholera vaccines. Oral immunization of mice with formalin-killed MS1342 bacteria gave rise to Ogawa-specific, Inaba-specific and cross-reactive serum antibodies that were detectable both by lipopolysaccharide (LPS)-specific ELISAs and as vibriocidal antibodies that are considered to predict protective efficacy. These responses as well as intestinal mucosal IgA anti-LPS antibody responses were fully comparable with those obtained by immunization with the internationally licensed oral cholera vaccine Dukoral ®. We propose that such a strain may form the basis of a single strain killed whole cell cholera vaccine protecting against cholera caused by either the Inaba or Ogawa serotype of V. cholerae O1.

Health-promoting factors in higher education for a sustainable working life : protocol for a multicenter longitudinal study
- 2020
-
Ingår i: BMC Public Health. - London : BioMed Central. - 1471-2458. ; 20:1

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The World Health Organization has highlighted the importance of health promotion for health service providers in order to ensure sustainable working life for individuals involved in providing health services. Such sustainability begins when students are preparing to manage their own future health and welfare in working life. It has been suggested that universities, employees and trainee health professionals should adopt or follow a salutogenic approach that not only complements the providing of information on known health risks but also favors health promotion strategies. This paper describes the study design and data collection methods in a planned study aiming to explore health-promoting factors for a sustainable working life among students in higher education within healthcare and social work. METHODS: This protocol describes a multicenter longitudinal study involving Swedish students on higher education programs in the healthcare and social work sectors. In 2018, the study invited students on seven education programs at six universities to participate. These programs were for qualification as: biomedical laboratory scientists (n = 121); dental hygienists (n = 87); nurses (n = 1411); occupational therapists (n = 111); physiotherapists (n = 48); radiographers (n = 60); and, social workers (n = 443). In total, 2283 students were invited to participate. Participants completed a baseline, a self-reported questionnaire including six validated instruments measuring health-promoting factors and processes. There are to be five follow-up questionnaires. Three while the students are studying, one a year after graduating, and one three years after graduating. Each questionnaire captures different health-promoting dimensions, namely: health-promoting resources (i.e. sense of coherence); occupational balance; emotional intelligence; health and welfare; social interaction; and work and workplace experiences/perceptions. DISCUSSION: This study focuses on the vastly important aspect of promoting a sustainable working life for healthcare and social work employees. In contrast to previous studies in this area, the present study uses different, validated instruments in health promotion, taking a salutogenic approach. It is hoped that, by stimulating the implementation of new strategies, the study's findings will lead to education programs that prepare students better for a sustainable working life in healthcare and social work.
